By shifting a fundamental property of computation, Princeton researchers have built a new type of computer chip that boosts the performance and slashes the energy demands of systems used for artificial intelligence.

Yueh-Lin (Lynn) Loo, Director of the Andlinger Center for Energy and the Environment and the Theodora D. ’78 and William H. Walton III ’74 Professor in Engineering, discusses the innovations needed to meet the challenges of a changing climate.

Despite progress in securing voting in the United States, many jurisdictions still use electronic voting machines that leave no paper trail. According to experts who gathered October 17 at Princeton, this is a serious vulnerability.

Investigators of the Borexino collaboration report the most detailed record to date of neutrinos produced by fusion reactions in the solar interior. Often called ghost particles because they pass through matter without leaving a trace, neutrinos can be used as proxies to determine the chain of reactions that make up solar fusion — the reaction that spews forth the sun’s tremendous energy.

It’s often easy to imagine balloons soaring or butterflies fluttering across a still image, but realizing this vision through computer animation is easier said than done. Now, a team of researchers has developed a new tool that makes animating such images much simpler.
